Making strides in the video arena, the a7S II Mirrorless Digital Camera from Sony offers an impressive blend of sensitivity,
dynamic range, resolution, and speed to benefit a versatile multimedia
workflow. Revolving around a full-frame 12.2MP Exmor CMOS sensor, the a7S II is
capable of internal UHD 4K recording at 30 fps with full pixel readout as well
as 1080p recording at up to 120 fps, all in the XAVC S format. For both stills
and video recording, the BIONZ X image processor also pairs with the sensor to
enable expanded sensitivity to ISO 409600, continuous shooting to 5 fps, and fast
intelligent autofocus with low-light sensitivity to -4 EV. Further enabling
working in difficult lighting conditions, 5-axis SteadyShot INSIDE image
stabilization compensates for vertical, horizontal, pitch, yaw, and roll camera
movements for sharper, smoother handheld recording.

Complementing the 4K recording capabilities is a redeveloped recording setup,
including the ability to utilize S-Log3 Gamma and S-Gamut3 in addition to
S-Log2, for increasing dynamic range values by up to 1300% to better match high-end
post-production workflows. For clearer monitoring potential, an enhanced Zebra
function better supports working with S-Log gamma settings and a Gamma Display
Assist helps to preview imagery with natural contrast by converting S-Log2 and
S-Log3 settings to the ITU709 gamma for easier on-camera viewing.

The a7S II is also characterized by a compact, yet robust, magnesium alloy body
design that incorporates a high 0.78x-magnification Tru-Finder OLED electronic
viewfinder. With a resolution of 2.36-million dots and a Zeiss T*
anti-reflective coating, this finder benefits working in a variety of lighting
conditions and is capable of previewing exposure and settings adjustments prior
to recording. A rear 3.0" 1,228,800-dot LCD screen is also available, and
features a tilting design to support working from high and low angles.
Additionally, built-in Wi-Fi connectivity with NFC allows you to pair mobile
devices to the camera for wireless sharing and remote camera control.

Full-Frame
Exmor Sensor and BIONZ X Image Processor

A 12.2MP full-frame
Exmor CMOS sensor and BIONZ X image processor work together to enable an
expansive dynamic range with minimal noise and notable sensitivity from ISO
100-102400, which is further expandable to ISO 50-409600. Coupled with the
large individual pixel size the 12.2MP sensor affords, this camera is
well-suited to use in low-light conditions.

The sensors design also features a new-generation RGB color filter array, as
well as a gapless on-chip lens design. Together, these two technologies enable
truly efficient light-gathering abilities that further reinforce the low noise,
high-sensitivity design. Furthermore, an anti-reflective coating has also been
applied to the seal glass of the image sensor to minimize surface reflections,
glare, and ghosting for contrast-rich, color-neutral imagery.

The sensor and processor combination also avail a wealth of performance-related
benefits to still shooting, including a Speed Priority continuous shooting rate
of 5 fps, or a 2.5 fps shooting rate with continuous AF. The Fast Intelligent
AF system employs 169 AF points, which is comprised of 25 contrast-detection
points and nine central AF points that have been split into 16 segments each,
in order to provide both speed and accuracy in low-light conditions down to -4
EV.

Internal
UHD 4K Recording and Full Pixel Readout

Internal recording of
UHD 4K movies is possible in multiple frame rates up to 30 fps and, based on
the 12.2MP resolution, full pixel readout is possible that is void of pixel
binning for higher quality imagery with reduced moiré and aliasing. Full HD
1080p recording is also supported in frame rates up to 120 fps, and both
resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper
with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x
slow-motion movie recording with the frame rate set to either 30p or 24p.

In addition to high-resolution internal recording, uncompressed HDMI output
also enables the use of an optional external recorder for clean 4K recording
with 4:2:2 sampling.

5-Axis
SteadyShot INSIDE Image Stabilization

Packed into the svelte
a7S II is a 4.5-stop effective 5-axis SteadyShot INSIDE image stabilization
system that compensates for five different types of camera shake encountered
during handheld shooting of stills and video. This allows users to confidently
use any lens, even adapted lenses, for critical imaging without encountering
blur from camera shake.

For long focal lengths, the system will correct for pitch and yaw adjustments.
Macro and high-magnification imagery, on the other hand, will benefit from the
inclusion of horizontal and vertical shift compensation. All shooting styles
will get usage out of the roll compensation. All 5 axes of stabilization will
function at all times, even when used with third-party lenses and adapters or
lenses with built-in optical stabilization.

Custom
Color Profiles and S-Log3 Gamma

Support is available for
the S-Gamut3.Cine/S-Log-3 and S-Gamut3/S-Log3 profiles that enable up to a
1300% wider dynamic range for smoother tonal and color gradations, along with
enhanced sensitivity and clarity in shadows and mid-tones. These profiles also
lend themselves to greater compatibility within a professional workflow and are
well-paired to the Cineon Log gamma curve for versatile post-production grading
and color control. The S-Log3 gamma setting also offers an impressive 14-stop
wide dynamic range for greater control over the highlights and shadows, while
the S-Gamut3.Cine profile can be used to mimic the qualities of scanned
negative film with a wide gamut comparable to the DCI-P3 color space.

In addition to the S-Log3 gamma, the popular S-Log2 settings are also
available.

Zebra
and Gamma Display Assist

An enhanced Zebra
function is ideally suited to working with S-Log gamma profiles and aids in
monitoring exposure values in high-contrast scenes. Video signal level targets
can be set from 0 to 109, and specific ranges can be set to make exposure level
adjustments easier.

In contrast, a Gamma Display Assist function is also available that displays
scenes with natural contrast when recording with S-Log settings. This function
converts imagery to the ITU709 profile for easier on-camera monitoring.

Timecode
and User Bit Settings

The a7S II has multiple
timecode recording options to meet different workflows. It has the standard Record
Run" mode that only advances the timecode when recording, as well as
"Free Run" timecode that advances the timecode even when not
recording, which can be great for syncing multiple cameras at live events. It
can also record timecode in both drop frame and non-drop frame modes. When
recording internally the a7S II is also able to output timecode via HDMI.

0.5"
2.36m-Dot XGA OLED Tru-Finder Electronic Viewfinder

With its 4-lens optical
system using double-sided aspherical elements the viewfinder faithfully
displays what will appear in your recording, including the effects of your
camera settings. Youll enjoy rich tonal gradations and improved contrast.
High-end features like 100% frame coverage and a 0.78x magnification enable
comfortable and stable eye-level composition.

In addition to the electronic viewfinder, a rear 3.0" 1,228.8k-dot LCD
monitor has also been incorporated into the design and can tilt 107° upward or
41° downward to better enable working from high and low angles.

Built-In
Wi-Fi Connectivity with NFC

Built-in Wi-Fi
connectivity enables the a7S II to instantly share imagery to mobile devices
for direct sharing online to social networking, via email, and to cloud storage
sites. NFC (Near Field Communication) is also supported, which allows for
one-touch connection between the camera and compatible mobile devices; no
complex set-up is required. Once connected, the linked mobile device can also
display a live view image on its screen and remotely control the cameras
shutter.

Additionally, PlayMemories Camera Apps are also supported via the built-in
Wi-Fi connection, and allow you to personalize the cameras features depending
on specific shooting styles. Apps are available to suit creating portraits,
detailed close-ups, sports, time lapse, motion shot, and other specific types
of imagery.
